Description

BOOKLET FORM PAPERBOARD PACKAGE FOR MEDIA DISCS

REFERENCE TO RELATED APPLICATION

[0001] This application claims the benefit of priority under 35 U.S. C. §119(e) of U.S. provisional application serial number 61/028,767 filed on February 14, 2008, which is hereby incorporated by reference in its entirety.

BACKGROUND OF THE INVENTION

[0002] The present invention relates generally to a closable storage package for a recording medium and, more particularly, to a package comprising a paper board book-like assembly for storing one or more discs.

[0003] Various types of planar discs are in use at the present time to record and store information which is to be retrieved by various means, such as by optical or magnetic means. Typical of such discs are compact discs in which information is digitally recorded by use of a laser beam and then read optically by a laser beam. Such discs are used to record audio information, such as musical renditions, video information such as visual images and digital information for use as read only and other memories for use in various applications, such as computer applications. In most instances, at the present time, such discs are sold with information already recorded thereon. In other applications, such discs are sold in blank form and are used by the customer to record information thereon. In the latter case, for example, optical discs are sold for use as computer storage media and are used in hard disc storage systems. As used herein, the terms media disc, compact disc, CD or disc are intended to encompass all such discs, whatever their size, for all known or proposed uses.

[0004] Compact discs containing laser recorded information are typically packaged in injection molded plastic enclosures designed to hold one or more CDs for protecting the discs during storage and shipment. Enclosures commonly used at the present time, such as the well known "jewel box," comprise a three piece assembly consisting of a base or bottom element, an insert or tray in the base/bottom element for positioning and supporting the disc in the base/bottom element, e.g., by a center projection (commonly referred to as a "rosette") which engages the periphery of the aperture in the center of the disc, and a lid or cover which is hinged to the base/bottom element and is closed thereon after the disc is mounted therein on the tray. Other enclosures may support a disc or discs within a booklet- like structure made partially or completely of paper or paperboard.

[0005] There remains a need for a simple, sturdy, environmentally friendly, attractive, and inexpensive to manufacture CD package that adequately protects the disc yet provides easy access thereto.

SUMMARY OF THE INVENTION

[0006] It is an object of the present disclosure to provide a package for holding discs that is easy to manufacture from paper board or similar suitable environmentally friendly and/or recyclable material and adhesive such that the finished package is sturdy and attractive.

[0007] The present disclosure is directed to a package for housing one or more discs in a booklet-like package including one or more pages comprising multiple plies some of whose material is partially cut away to provide a holding space for at least one disc. Variations of the illustrative embodiments are also within the contemplation of the present disclosure, including variations in the size, shape, material, and number of the pages, and the size, shape, number and location of the cutaway areas for holding discs.

[0008] It should be appreciated that the present invention can be implemented and utilized in numerous ways, including without limitation as a process, an apparatus, a system, a device, and a method for applications and from other suitable materials now known and later developed. These and other unique features of the system disclosed herein will become more readily apparent from the following description and the accompanying drawings.

DESCRIPTION OF EXEMPLARY EMBODIMENTS

[00018] The present disclosure is for a book-like package for optical media or other items. The advantages, and other features of the package disclosed herein, will become more readily apparent to those having ordinary skill in the art from the following detailed description of certain exemplary embodiments taken in conjunction with the drawings which set forth representative embodiments of the present invention and wherein like reference numerals identify similar structural elements whenever possible.

[00019] All relative descriptions herein such as left, right, up, down, topside, underside and the like are with reference to the Figures, and not meant in a limiting sense. The illustrated embodiments can be understood as providing exemplary features of varying detail of certain embodiments, and therefore, unless otherwise specified, features, components, modules, elements, and/or aspects of the illustrations can be otherwise combined, interconnected, sequenced, separated, interchanged, positioned, and/or rearranged without materially departing from the disclosed systems or methods. Additionally, the shapes and sizes of components are also exemplary and unless otherwise specified, can be altered without materially affecting or limiting the disclosed technology to holding discs exclusively.

[00020] Exemplary embodiments of the present invention are illustrated in FIGURES

1-8, in which there are shown improved optical media packages made from paper and adhesive. In brief overview, the packages are made from folded sheets of (generally) a lighter weight sheet material (such as paper) with plies of a (generally) heavier weight sheet material (such as paperboard) sandwiched between. Cutout areas are provided in the heavier weight (paperboard) to receive optical media.

[00021] FIGURE 1 shows certain parts the package prior to assembly. A first sheet of paper 10 is folded into panels 12A and 12B along a score line 14. A cutting line 18 may be provided, which is shown in dashed line in the drawing; this cutting line 18 may or may not be indicated by a visible marking. Beyond the cutting line 18 are trim panels 12C and 12D that may be removed in later trimming operations. A central aperture 16 may be provided in one or both panels 12A and 12B. A peripheral aperture 17 may also be provided in one or both panels 12A and 12B.

[00022] A second sheet 20 is folded into panels 22 A and 22B along a score line 24. As with the first panel, cutting line 28, central aperture 26, and peripheral aperture 27 may be provided in the second sheet 20.

[00023] Shown between first sheet 10 and second sheet 20 is third sheet 30, which in the assembled configuration may hold optical media 50. The third sheet 30 may for example be formed of a paperboard, such as a paperboard having a thickness of about 0.036 inches. A cut line 34, shown as approximately "U" shaped, defines a removable region 32B that will ultimately be removed to make room for the optical media. However, at this point of the assembly, removable region 32B is still connected with the rest of third sheet 30, represented by permanent region 32A. A cutting line 38 is shown on third sheet 30.

[00024] FIGURE 2 shows the parts of FIGURE 1 having been brought together so that the third sheet 30 is sandwiched between the first and second sheets, forming an assembly 100. This may be done by applying adhesive to both sides of third sheet 30, excepting the removable region 32B, then placing the first sheet and second sheet on opposing surfaces of third sheet 30. The assembly as shown in FIGURE 2 is an example of a stage in the construction of a multi-page booklet form package for holding one or more optical media. However, the assembly 100 as shown in FIGURE 2 may be utilized as a package for a single disc, in which case central aperture 26 and peripheral aperture 27 may be omitted from the second sheet.

[00025] FIGURE 3 shows a step in the assembly of a multi-page booklet-like package for holding one or more optical media. In this case additional pages 210 are provided within the package. Pages 210 each may comprise for example a first sheet (e.g. a lighter paper sheet as previously described) and a third sheet (e.g. a heavier paperboard sheet as previously described). The pages may be adhered together as explained in FIGURE 2.

[00026] FIGURE 4 A shows a top view of the assembly as shown in FIGURE 3, before adhering the parts together. It can be seen that the structure includes six of the third sheet 30, separated by five of first sheet 10, all between a "front cover" of first sheet 10 and a "rear cover" of second sheet 20. All of the facing surfaces of these sheets would be glued together as explained in FIGURE 2, which then gives the package 200 as shown in top view in FIGURE 4B, where the internal pages 210 are each shown as a unit.

[00027] After the component sheets have been glued together to form as many connected pages as desired, the package may be cut along cutting lines 18, 28, and 38, leaving package 200 appearing as shown in FIGURE 5. The removable regions 32B are now free to be removed from the assembly, and their removal leaves internal spaces to receive optical media 50 (shown fully enclosed in the package) and optical media 51 (shown partly removed from the package). Removal from the package is facilitated by the peripheral apertures 17 which permit the disc edge 57 to be grasped, or by the central apertures 16 that permit the disc to be lifted by placing a finger in the disc hub opening 56.

[00028] Besides cutting the package along cutting lines 18, 28, and 38 as described, the other edges may also be trimmed or cut, excepting the joined edge that serves as the spine (e.g., along fold 14 and its counterparts). The removable region 32B may be recycled, or it may be used as feed stock for other uses. It may be pre-printed before assembly, to form promotional materials, coupons, cards, and other items useful to the purchaser or the manufacturer of the package.

[00029] FIGURE 5 shows the appearance of the package 200 with only the front cover (represented by panel 12A) and the rear cover (represented by panel 42B, also showing its cutting line 48) opened outward. FIGURE 6 shows another view of the package, with the pages 210 splayed somewhat apart to show a more typical use situation.

[00030] Since the facing surfaces at any "page" in the page in the package are made of a single continuous sheet of paper (such as facing surfaces 12A and 12B), a continuous graphic image may be printed without any disruptive discontinuities at the binding edge, which is merely the fold 14 between the facing panels.

[00031] FIGURE 7 shows another embodiment as package 300 in which front pages

301, 302, 303, and 304 and back pages 317, 318, and 319 do not house optical discs. Such non-disc pages may occur in any desired number and may be located anywhere in the package, including interspersed between pages that house discs. Non-disc pages may include third sheet 30 if desired, but often would not include this thicker piece of material.

[00032] The package may contain one or more media discs, and each page may contain one or more discs. FIGURE 8 shows another embodiment as package 400 wherein the pages each may hold two discs, for example discs 50 and 51 inward toward the "binding edge and discs 60 and 61 housed toward the outward edge of the package. In the embodiment of package 400, front pages 401, 402, 403, and 404 and back pages 417, 418, and 419 do not house optical discs.

[00033] The packages may contain items other than media discs. Although in some embodiments the packages may be made from paperboard having a thickness of about 0.036", and paper of various thicknesses, other types and thicknesses of materials may be utilized as are known in the packaging arts. The third sheet 30 in particular may be formed of more than one ply or more than one material. For example, it may be bleached board, kraft board, dyed or otherwise colored board. The package may use multiple style covers, including for example a hard cover (for example, as used on case bound books, coffee table books or hard back novels) or thick paperboard may be used for the cover.

[00034] The removable region 32B may be rectangular as shown in the Figures, or it may have other shapes that are suitable to accommodate an optical disc or other item desired to be housed in the package. For example, the bottom periphery of removable region 32B may be semi-circular to fit the perimeter of a disc, or it may have a polyhedral shape. The shape of the removable region 32B may be simple (e.g. linear, curved) or complex. The shape and size of central aperture 16 may be varied, or it may be omitted. Likewise the shape and size of peripheral aperture 17 may be varied or it may be omitted. Either aperture may appear on one, both, or neither of the sheets of paper that are glued to third sheet 30.

[00035] As noted above, the packages can be formed using a variety of materials or substrates. For example, PRINTKOTE EAGLE ®, which is composed of at least 10% post consumer recycled material, can be used. Moreover, a polymeric substrate such as calendered POLYLITH® GC-3 can be used. POLYLITH® substrate is manufactured by Nanya Plastics of Taiwan and is distributed in the U.S. by Granwell Products, Inc. POLYLITH® substrate is primarily formed using polypropylene resin and minerals comprising inert calcium carbonate and titanium dioxide and the resulting substrate is strengthened by calendaring.

[00036] While the invention has been described with respect to exemplary embodiments, those skilled in the art will readily appreciate that various changes and/or modifications can be made to the invention without departing from the spirit or scope of the invention.
